Jejunal Diverticulosis: An Atypical Lead Point for Small Bowel Volvulus

The occurrence of small intestinal diverticula is relatively infrequent compared to its counterpart in the large bowel. Duodenal diverticula exhibit a significantly higher prevalence within the small intestine compared to jejunoileal diverticula, with a ratio of five to one. The occurrence of jejunoileal diverticula exhibits considerable variability and has been documented to range from 0.5% to 2.3% in radiographic series, while autopsy studies have reported rates as high as 7%. We present the clinical details of a 65-year-old male patient who sought medical attention due to a constellation of symptoms, including abdominal pain, vomiting, and obstipation. After adequate resuscitation with IV fluids and preoperative preparation, the patient was transported to the operating room for an emergency exploratory laparotomy. Multiple jejunal diverticuli were identified in the proximal jejunum at the antimesenteric border, less than three feet from the duodenojejunal (DJ) junction. The terminal ileum was found to be 360° rotated counterclockwise around the small bowel mesentery, causing the small intestine to appear congested; however, after clockwise de-rotation, the small bowel regained its normal color. Adhesiolysis and small bowel decompression were performed, and the patient had an uneventful recovery.
